Color classification system

Abstract

The present invention relates to a method for classifying colors and grey shades, including the classification of colors in a matrix, in which the colors in the matrix belong to a same subfamily and in which the position of a color in the matrix is determined by the degree of color degree of saturation of chroma and the degree of greying of the color, characterised in that the scale for the degree of color degree of saturation of 10 chroma as well as the scale for the degree of greying are linear, in which the scale for the degree of greying depends on the scale for the degree of color degree of saturation of chroma and in which the greying steps are dynamic in function of the color degree of saturation of chroma.
